Abstract
A cartridge for simultaneously dispensing at least two different materials includes an elongated hollow housing having at least one partition extending laterally and longitudinally thereof to provide at least two chambers for holding the respective materials. A plunger sliding within the housing severs or slits the partition so that it can be stored during operation outside of the respective chambers. The partition may be coiled up or it may be directed laterally around the plunger so that it is stored adjacent an internal wall of the housing.
Claims25
A cartridge for simultaneously dispensing at least two different materials, said cartridge comprising:
- (a) an elongated hollow housing;
- (b) at least one partition within said housing extending laterally and longitudinally thereof to divide the housing into at least two chambers each for holding one of said different materials;
- (c) a plunger received in said housing for movement longitudinally thereof;
- (d) a dispensing orifice in said housing for each of said chambers;
- the plunger comprising:
- (e) piston means having a first face for acting on said materials to dispense them from said housing, said piston means including means for sealingly engaging said housing and said partition;
- (f) severing means following said piston means and being spaced from said materials by said piston means, said severing means being adapted to sever said partition from said housing;
- and
- (g) means for storing said severed partition so as not to interfere with the operation of said cartridge.
